Its description reads:
“Dugu Linghe left behind this seal, along with a mountainside strewn with bones. The Baishan Sect slaughtered her family. She answered by bathing Baishan in blood.
Years later, Bi Taotao enshrined the seal in a small shrine dedicated to Dugu Linghe. It remained there until Perfect Transcension spread throughout Baishan. Then Ju, a disciple of the Baishan Sect, stole the seal, intending to present it to those carrying out Perfect Transcension.”
